ANTISORE MATTRESS.

Specification of Letters Patent.

Patented Oct. 17, 1905.

Application filed April 18,1905. Serial No. 256,240.

To all whom it may concern:

Be it known that I, ELIE LAMBOTTE, surgeon,a subjectof the King of Belgium,residing at Brussels, Belgium, have invented a new and useful Improvement in Antisore Mattresses; and I do hereby declare the following to be a full, clear, and exact description of the same.

It is a well-known fact that when apatient is obliged to rest a long time upon certain points of his body the latter gets sore by lying. Heretofore various means have been invented for avoiding this objection, said means having chiefly for their object to improve the consistence and the form of the surfaces upon which the patient is deposited and to provide devices whereby the patient may be lifted and displaced intermittently.

My present invention relates to devices of this kind, and has for its object to provide a mattress the surface of which is formed of movable sections adapted to be loweredand raised alternately for supporting the patient and changing alternately the places upon whichhe rests without obliging the patient to move himself.

With this object in view my invention consists of the construction, combination, and arrangement of parts fully described and claimed hereinafter, reference being bad to the accompanying drawing, showing one form of embodiment of my invention.

The improved construction comprises a bedstead 1 of suitable size and design, to the iongitudinal sides of which are attached angleirons 2. Arranged at each end of said angleirons are stationary brackets 3, in which are journaled longitudinal rocking shafts 4, each of which is provided at one end with a crank 5, pivotally connected. to sliding bars 6, movably arranged in sleeves 7, made one with a casing 8, secured to a bar 9 of the bedstead. Journaled within said casing is a shaft 10, carrying a suitable cam 11 and an operating-handle 12, so that when said handle is moved alternately to the right and left hand sides the cam 11 imparts corresponding sliding movements to the bars 6 6, which cause the rocking shafts 4: 4 to rock in their brackets 3. The shafts 4 carry rings 13, to which are attached the straps 14, arranged transversely and forming the surface upon which the patient is to be laid.

The rings 13 are alternately fastened on the movable shaft4 and the stationary angle-iron 2, so that each strap is fixed at one end and movable at the opposite end, the successive straps forming a sort of open cooperating floors adapted to be moved as follows: One

series of straps is lowered, while the other series of straps remains in position to support the patient. The first series is again raised until it supports the patient, when at the same time the second series of straps is lowered in turn and relieves the pressure on the patients body and then again raised without the patient ceasing to occupy the same horizontal plane. The straps 14 are covered with a suitable stuffing varying according to circumstances in order to deaden the successive contacts of the straps. The successive straps are arranged so that the complete surface may accommodate itself to the body of the patient.

The construction herein described and shown may be advantageously used with seats of any kind z'. 6., seats for theaters, railwaycars, ofiices, and the like.

Having fully described my invention, what I claim, and desire to secure by Letters Patcut, is

1. In an antisore mattress, the combination with a bedstead, of two rocking shafts, journaled along the longitudinal sides of the bedstead, transversely-arranged straps, the ends of which are alternately attached to said shafts and to the bedstead, and means for rocking said shafts, substantially as set forth.

2. Inan antisore mattress, the combination with a bedstead, of suitable brackets, arranged on the four outer corners of the same, two longitudinally-arranged rocking shafts journaled-in said brackets, rings on the rocking shafts, suitable straps attached to said rings, the latter being alternately secured to the movable shaft and a stationary part, and means for rocking said shafts, substantially as set forth.

3. In an antisore mattress, the combination with a bedstead, of suitable brackets, arranged on the four outer corners of the same, two longitudinally-arranged rocking shafts journaled in said brackets, rings on the rocking shafts, suitable straps attached to said rings, the latter being alternately secured to the movable shafts and a stationary part, cranks to this specification in the presence of two subsecured on one end of the rocking shafts, eccenscribing Witnesses. trio-bars pivotally connected to said cranks a suitable eccentric rotatably arranged on the ELIE LAMBOT 5 frame of the bedstead, and means for actuat- Witnesses:

ing the eccentric, substantially as set forth. J OSE WVAGNER,
